Have u noticed that it’s a hand print? 🙂 Although this wordle is based on cells, Its meant to symbolize the start of biology. In other words, the very beginning..where the cell comes into play, being the start of basically EVERYTHING in all. Its also meant to symbolize all those who have left their mark in biological history biological history. Many scientists have changed the way we see things such as Robert Hooke who discovered and described the cell. There is Albert Einstein, Neil’s Bohr (he discovered the atom), Dmitri Medelev, Sir Isaac Newton among many others 😀

It is known that Robert Hooke discovered and described the fundamental unit of all living things cells, this is…..the cell. A cell is the smallest unit that is capable of performing life functions such as growth, metabolism, stimulus, response and even replication. :O Cells are known to have various shapes and sizes as they all possess different functions.

Most cells are relatively small. This is because as size increases; volume increases resulting in a longer diffusion time. Scientists have estimated that our bodies contain somewhat 75 to 100 trillion cells! They range in size between 1 to 100 micrometers and cannot be seen by the naked eye, OBVIOUSLY! But it can be seen through microscopes. Without which cell biology would not have been possible. It was through these microscopes that scientists were able to carry out the indepth study of the cell. There are two types of microscopes today that can do this, The Scanning Electron Microscope and the Transmission Electron Microscope which can give detailed images of cell structures.
